SPECIFICATION forming part of Letters Patent No. 782,277', dated February 14, 1905.

Application led July 20,1903. Seria1No.166,231.

Be it known that I. EizNs'r G. Renna. a citizen of the United States, residing at Hamilton. Butler county. Ohio. have invented a new and useful Improvement in Glazing-Machines. of which the following is a specitieation.

)ly invention relates to glazing-machines of the class adapted to apply glazing liquid to the Vface of bisque tile; and the objects of my improvement are to provide means to regulate the quantity of glazing liquid applied to the tile. to deposit the glazingl on the Jface of the tile in uniform thickness. to prevent the glaze from contact with the edges of the tile. to facilitate the glazing operation, and dispense with manual labor. These objects are attained in the following-described manner. as illustrated in the accompanying drawings, in which- Figure l is a front elevation of my device with parts in section; Fig. 2, a side elevation with parts in section; Fig. 3, a plan ot' the pump-spout; Fig. I, a transverse section of the pump-spout and portions of the coatingcylinder; Fig. 5, a` portion of the cylindercovering; Figs. 6 and 7, modilied forms of construction of said covering; and Fig. S, a modified Yform of construction, showing a plural number of coating-cyliiulers on the same tank.

In the drawings, 8 represents a tank Vformed with a semicylindrical bottom and provided with bracket 9. wherein crank-shaft 1l is journaled and rotated from the source of power by means of drive-pulley l2, secured thereon. ,Pulley 1?). mounted on the lsame shaft` transmits power through belt l-L and pulley to coating-cylinder 10, which is joui-naled in the top portion of the tank. The face of the Cylinder is covered with india-rubber or other suitable material lilled with indentations or small cups lo. Pressure-roll lT is mounted directly over the cylinder and is movable vertically in slotted bearings 1S. Said roll is intended to exert a light pressure on the bisques i9 as they are passed between it and the cylinder. and if its weight is not sutticient its pressure may be reinforced by springs in the usual manner. Said bisques or tiles are placed on feeding-table 91 and passed between the roll and the cylinder and upon endless deliveryapron 22. Said apron is caused to travel at the same speed as the periphery of the cylinder by means of sprocket-chain Liconnecting wheel 24, secured on the cyliiuler-shat't 25, with wheel 26. secured on the driving-roll 27 of the apron. Pump 31, adapted to throw a continuous stream, is secured within the cylinder near one of its sides and actuated by crank 32, mounted on the crank-shaft. Spout 81, adjustably secured or swiveled on the pump at 35, is formed with a double bend and extended near to and across the face of the cylinder and parallel thereto. The extremity of said spout is closed. and discharge-opening 36 consists of a narrow slot formed in the side of the spout toward the cylinder and to the extent of the width of its face. 'lhe entrance-opening 3T of the pump is located at the bottom of the tank and near one of its sides, and agitator 3S, preferably in the form of a helical conveyer, is journaled to rotate within the bottom portion of the tank to agitate and move the glazing liquid therein toward the said pumpopening'. Said agitator is rotated by means of a chain l engaging' with wheels Q and i3, that are secured on the respective cylinder and agitator-shafts.

ln operation the glazing liquid is carried by the pump from the bottom of the tank and discharged in a continuous sheet of even thickness through the slot in the spout upon the cupped face of the cylinder. lt is thence carried by the rotation of thecylinder in contact with the face of the bisques during their pas-` sage. over the cylinder and in contact therewith under the pressure of the roll. '.lhe bisques are so absorbent that the glazing' liquid upon contact therewith coiigeals and adheres to their faces without contact withtheir edges. 'lhe quantity or thickness of the glazing lluid deposited on the bisques may be regulated by the vertical adjustment of the pump-spout in relation tothe face of the cylinder. The higher up on the face of the cylinder the glazing liquid is delivered the more will be retained in the cups and carried in contact with the bisques without being spilled back in the tank.

A series of machines may be coupled in train for the passage of the bisques suceesder, of means at intervals on the face of the sively therethrough to deposit additional glaze of different colors in patches for the purpose of producing the desired blend or mottled color after being' ired in the kiln. For this purpose the different machines may be provided with cylinder-covers of different surface configurations or with larger cups 44, preferably wider at the bottom, as shown in Fig. 6, and distributed at desired intervals. or a series of Sponges 45 may be caused to project at irregular intervals from the otherwise smooth surface of the cylinder or its elastic cover, as shown in Fig. 7.

A plural number of coats of the same glaze may be applied to the face of the bisqueswhen desired by providing a plural number of coating-cylinders for the same tank, as shown at 46 and 47 in Fig. 8. In this form of construction an adjustable pump-spout should be provided for each cylinder to discharge the contents of the tank thereon in a constant stream or sheet and in the desired quantity.

Having fully described my improvement, what I claim as my invention, and desire to secure by Letters Patent of the United States,

1. The combination with a tank, a rotative cylinder mounted thereon, a pressure-roll mounted thereover, and a feeding-table, of adinstable means to deliver the contents of the tank in a continuous stream at different elevations upon the face of the cylinder.

2. The combination with a tank, a rotative cylinder, an elastic covering' thereon and formed with cups in its surface, of a pump arranged to deliver the contents of the tank in a continuous stream upon the face of the cylinder-covering.

3. The combination with a tank, an agitator movable therein, a rotative cylinder mounted across the top of the tank, a pressure-roll mounted over the cylinder, a feeding-table leading toward and a delivery-apron leading from the top of the cylinder, of a pump arranged to deliver in a continuous stream the contents of the tank upon the face of the cylinder.

4. The combination with a tank a rotative cylinder mounted therein, and an elastic cover secured on the cylinder and containing a series of cups in its surface, each cup being enlarged toward its bottom, of means to deliver the contents of the tank in a continuous stream on the cylinder.

5. The combination with a tank, a cylinder mounted to rotate therein, and a pump adjustable to deliver the liquid contents of the tank at dili'erent elevations on the face of the cylincylinder adapted to retain more of the liquid than other portions of its surface.

6. in combination a tank, an agitator therein, a plural number of cylinders mounted in the same plane, means to rotate them in the same direction, and a pump arranged to deliver the liquid contents of the tank on the upper portion of the face of the cylinders.

7. The combination of a tank,a cylinder having an elastic face and mounted in iiXed bearings to rotate in a vertical plane, averticallyadjustable spout communicating With the tank and formed with a discharge-slot adjacent to, and parallel with, the cylinder, whereby the contents of the tank may discharge on the cylinder at different elevations.

8. In combination, a tank, a rotative cylinder with an elastic face, and apump arranged to deliver the liquid contents of the tank on the upper portion of the face of the cylinder.

9. 1n combination, a tank, a rotative cylinder having an elastic face filled with indentations, and a pump arranged to deliver theliquid contents of the tank on the upper portion of the face of the cylinder.

l0. in combination, a tank, a rotative cylinder having an elastic face containing indentations, and a pump with an adjustable spout arranged to deliver the liquid contents of the tank at different elevations thereon.

ll. In combination, a rotative cylinder, a feeding-table, a tank, an agitator therein. and adjustable means arranged to deliver the liquid contents of the tank at different elevations onthe face of the cylinder.

l2. The combination of a tank, a'cylinder mounted to rotate in a vertical plane, aspout formed with a slot parallel with and adjacent to the face of the cylinder and of substantially the same length thereof, said spout being adjustable to different elevations in relation to the cylinder, and means arranged to convey the contents of the tank to the spout.

13. The combination of a tank, a cylinder mounted to rotate in a vertical plane and provided with an elastic face, an adjustable spout communicating with the tank and with the face of the cylinder through a discharge-slot formed therein parallel with the cylinder and substantially the same length thereof,'whereby the contents of the cylinder may be evenly distributed at diderent elevations on the face of the cylinder.
